The symptoms you describe sound like an allergic reaction
in both eyes. If the crusting is along the eyelid margin you probably have blepharitis( eyelid infection
) along with this. Try a course of oral antihistamines to reduce lid inflammation. Wash your lids with warm water and a mild soapy solution made with warm water and a few drops of baby shampoo to remove crusts. Start some lubricating eye drops and an antibiotic eye ointment on the eyelids. Wait for a few days and the swelling should subside. Your vision should improve as well.
